摘要： 为了研究不同锅炉负荷下，改变炉膛内不同高度O₂含量对水冷壁硫化物型高温腐蚀的影响，对1 台660 MW
FW型式的W型火焰锅炉建立了模型，在3种负荷条件下分别以3种典型二次风配比作为边界条件模拟了煤粉燃烧过程。

Abstract: In order to study the effect of changing the O₂ content at different heights in the furnace on sulfide-type high temperature
corrosion of water wall under different boiler loads, this paper established a model of a 660 MW FW type W-flame boiler
and simulated its pulverized coal combustion process with three typical secondary air ratios as boundary conditions under three
load conditions.

Key words: W-flame boiler; reducing gas; secondary air ratio; numerical simulation
